These supplementary requirements apply to fuse-links for the protection of batteries and battery systems, including, but not limited to terminology, for electricity storage in equipment for circuits of nominal voltages up to 1 500 V d.c. Their rated voltage may be higher than 1 500 V d.c. The object of these supplementary requirements is to establish the characteristics of Battery fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics, provided that their dimensions are identical.

2 Part 7: Supplementary Requirements for fuse-links for the protection of batteries and battery systems
4 FOREWORD
6 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
7 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
8 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
9 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
10 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
11 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
12 in the subject dealt with may participate in this preparatory work. International, governmental and non17
13 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
14 with the International Organization for Standardization (ISO) in accordance with conditions determined by
15 agreement between the two organizations.
16 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
17 consensus of opinion on the relevant subjects since each technical committee has representation from all
18 interested IEC National Committees.
19 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
20 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
21 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
22 misinterpretation by any end user.
23 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
24 transparently to the maximum extent possible in their national and regional publications. Any divergence
25 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
26 the latter.
27 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
28 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
29 services carried out by independent certification bodies.
30 6) All users should ensure that they have the latest edition of this publication.
31 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
32 members of its technical committees and IEC National Committees for any personal injury, property damage or
33 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
34 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
35 Publications.
36 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
37 indispensable for the correct application of this publication.
38 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
39 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
